I adore a great Margarita, but I'm not too fond of all the sugary pre-made mixers that are often added to it. I like making mine super clean and refreshing. 
 
Yield 1 Margarita
 
1½ oz. Siete Leguas Silver Tequila, or any high-quality tequila you prefer
½ oz. Cointreau
½ a lime, juiced 
1 lime wedge
Ice
 
In a glass, add the first three ingredients and stir. Add ice and a lime wedge and drink up.

Cheers, and enjoy!
